Patent No. 283,535, dated August 21, 1883.

Application filed May 3, 1883. (No model.)

To all whom it may concern,.-

Be it known that I, Circus I. TITTLE, a citizen of the 'United States,residing at Johnstown, in the county of Cambria and State ofFennsylvania, have invented a new and useful Machine for StraighteningRails, of which nal vertical sectional view, and Fig. tis a side viewillustrating a modification in the mechanism for operating the machine.

The same letters refer to the same parts in all the iigures.

A in the drawings designates the base, upon which. two uprights or sideplates, 'B B, are bolted or otherwise secured; Said side plates havebearngsfor atransverse roller, C, which Ais provided between the saidside plates with a spiral iiange or worm, D.

rlhc upper edges of the side plates, B, are provided, directly above theroller C, with dovetailed recesses E, to receive a transversely-slidingplate, F, on the upper side oi' which are secured two blocks, G G, thclower inner corners of which have recesses H, adapted to receive theflanges of a rail, the web of which will fit between the inner ends ofthe blocks G. Similarly-constructed blocks I are secured upon the endsof the side plates, B, as shown.

The under side of the slide F isv provided with a groove, J, t0 receivethe spiral liange or worinD of the roller C. It will be seen that byoperating the latter the said slide may be forced to either side, asdesired. Frictionrollers may be arranged at the points of contact; butthis is not essential.

The ends ofthe side plates, 13 are provid- 'ed with brackets K K,forming Vhearings for transverse rollers L, which serve to support therail during the operation of straightening.

Power maybe applied to the roller C bythe following mechanism:

' M is a bevel-gear secured upon the end of the said roller, andengaging pinions N N, which are mounted loosely upon the powershaft O'.

I P are friction-wheels sliding upon the shaft, upon which they arefeathered in the usual manner, and adapted to engage .recesses in theends of the pinions.

The pinions may be simultaneously moved upon the shalt by means oflevers Q Q, connected by a rod, R. this mechanism either pinion maybeoperated, so as to revolve the gear-wheel and roller in eitherdirection.

In Fig. of the drawings I have shown a different mechanism for operatingthe roller C, which consists simply of a cog-wheel, S, se- ,cured uponthe end of said roller, and engaging a longitudinally'-sliding rack, T,operated by hydraulicpower. By either of these means the movement of theroller may be readilyr reversed and the motion may be. easilycontrolled. I donot, however, wish to be understood as limiting myselfto either of these applications of power, as modiiications might be madein this respect without departing from the spi-rit of my invention.

The operation of my invention will be readily understood from theforegoing description, taken in connection with the drawings heretoannexed. The rail to be straightened is run in upon the rollers Lbetween the blocks G G and I I, and is held securely against lateraldisplacement by the end blocks, I I, while-the slide carrying the blocksG G is moved in either direction by the described mechanism.

I claim as my invention and desire to sevIn a machine for straighteningrails, .the combination ofthe sides rhavin g fixed holdingblocks, thetransversely-movable slide having suitable holding-blocks ou its upperside, a spirally-flanged roller arranged under the said slide andengaging a groove in its underside, and mechanism for revolving the saidroller in either direction, substantially as set forth.

In testimony, that I claim the foregoing as my own I have hereto affixedmy signature in presence of two witnesses.
